All OMIM entries have links to many other genomic resources as detailed in the 2015 database report. Only those links with a topical link for that gene or phenotype are listed in the External Links box to the right of the entry, and the link takes the user to the relevant page. A comprehensive list of all links is available from the Help link on the top of every page and takes one to the home page for that resource. In addition to the External Links box, there are links found in various places in an OMIM entry. OMIM includes links to many variation resources, including ExAC and gnomAD (9), as well as locus specific databases registered with the HGVS. All OMIM variants are cataloged in ClinVar (10) and updated nightly to that resource. The ClinVar and ExAC links are available from the Allelic Variant section of an OMIM gene entry and in the Allelic Variant table view option.
